Chop the green onion to 3 mm sizes. Mince the ginger.
In a small frying pan, heat the canola oil. Add in the chopped green onions, ginger, and dried red pepper, and cook in medium heat. Stir occasionally to avoid charring. Once the green onions turn brown, stop the heat. The Blacked Green Onion and Oil is ready! *The green onions cook very fast with residual heat, so please take precaution.
